The remote work era may be coming to an end — if companies can afford to keep their offices open

• Most companies mandate employees come into the office for a certain number of days, a Robin survey found.  
• 52% of businesses surveyed require workers to come into the office four times a week. 
• Still, the majority of office spaces aren't fully occupied, which can be costly. 

Companies are increasingly requiring their workers to return to the office — if they can afford it, a recent survey suggests.

Workplace strategy firm Robin surveyed more than 500 US business owners and facilities managers across industries like technology, finance, and construction to see how companies are using their offices.
